In this study, the gross calorific value (GCV) of coal was accurately and rapidly determined using eight artificial intelligence models based on big data of 2583 observations of coal samples in the Mong Duong underground coal mine (Vietnam). Accordingly, the volatile matter, moisture, and ash were considered as the key variables (inputs) for determining GCV. Seven artificial neural network ...

Gross calorific value (GCV) is one of the essential parameters for evaluating coal quality. Therefore, accurate GCV prediction is one of the primary ways to improve heating value as well as coal production. A novel evolutionarybased predictive system was proposed in this study for predicting GCV with high accuracy, namely the particle swarm optimization (PSO)support vector regression (SVR ...

These fuels can replace up to 40% of South African coal in the clinker precalcining process. By replacing 40% of existing coal, alternative fuels such as P. j wood, P. j leaf, P. j charcoal, used tires, and optimized fuels could potentially reduce CO 2 emissions by 2%, 9%, 9%, 21%, and 17% respectively. Furthermore, these alternative fuels ...
